Over 65% of Canadians have a least one cup of coffee throughout the day. Coffee is one of the most consumed beverages where many believe they can't live without it. But, how much caffeine is too much caffeine?
When we think caffeine, we often think coffee but there are so many other sources of caffeine that we put into our body that sometimes, we aren't even aware of.
Harvard School of Public Health states these items as having sources of caffeine:
Coffee. 1 cup or 8 ounces of brewed coffee contains about 95 mg caffeine. The same amount of instant coffee contains about 60 mg caffeine. Decaffeinated coffee contains about 4 mg of caffeine. Learn more about coffee.
Espresso. 1 shot or 1.5 ounces contains about 65 mg caffeine.
Tea. 1 cup of black tea contains about 47 mg caffeine. Green tea contains about 28 mg. Decaffeinated tea contains 2 mg, and herbal tea contains none. Learn more about tea.
Soda. A 12-ounce can of regular or diet dark cola contains about 40 mg caffeine. The same amount of Mountain Dew contains 55 mg caffeine.
Chocolate (cacao). 1 ounce of dark chocolate contains about 24 mg caffeine, whereas milk chocolate contains one-quarter of that amount.
Energy drinks. 1 cup or 8 ounces of an energy drink contains about 85 mg caffeine. However the standard energy drink serving is 16 ounces, which doubles the caffeine to 170 mg. Energy shots are much more concentrated than the drinks; a small 2 ounce shot contains about 200 mg caffeine. Learn more about energy drinks.
Supplements. Caffeine supplements contain about 200 mg per tablet, or the amount in 2 cups of brewed coffee.
